The portable electric lamp forming the subject matter of rectangular casing l which is ends. ing is In the middle of one side or" the provided a cylindrical pocket or well In this pocket are mounted to invention has a rounded at both casmy present swing diamet-j rically opposite each other a pair or arms 3 and 4 which curve toward each other and have the ends thereof. Th nected to lug 5 swiveled between the outer e pair of arms are thus con gether at their outer ends and swing as one into and out of the pocket 1 as illustrated in Figure 2. The lug 5, which is swiveled between the outer ends of the arms, supports the light head 6 and permits this head to swing in an are between the arms 3 and 4:. The light head carries at the back a cover 7 and on this cover dle 8 with which manipulated.

is provided a suitable hanthe covei and the head is,

When the lamp is not used, the light head 6 is nested intothe 2 and this is done cylindrical pocket or well by turning the light head 6 downwardly between the arms 3 and 4 while simultaneously swinging these arms in the opposite direction down into the pocket until the cover? rests on the casing and has closed the top of the pocket 2' as illustrated in dotted lines in Figure 2. A double jointed action is thus provided this makes it possible to arms and the head out of as above described.

for the arms and head" and quickly swing the or into the pocket In closing the pocket'2 the edge of the cover 7 engages into thecircular sealing channel"v 9 surrounding the pocket 2. I a

To use the lamp the cover 7 and head 6 are lifted and gradually swung outwardly while the arms 3 and 4' s cal pocket in the wing up out ofthe cylindricasingto a point where the head is free to be swung individually to assume the angle which will direct the light to the spot which is to be lighted. As illustrated in dotted lines in Figure 1, the head may be placed even into a vertical position.

As illustrated in Figure 1, sufficient room is provided within the casing 1 between the pocket 2 and the rounded ends to accommodate the dry cells and 11 one at each end of the casing. These cells are inserted into the casing by removing the back 12 thereof, suitable locking means being provided to removably hold the back in place on the casing.

The two electric cells are electrically connected in series with each other, a switch and the light 13. This connection is diametrically illustrated in Figure 3. The switch illustrated in this figure is automatically operated when the arms 3 and 4: are raised or lowered. As illustrated in Figure 1 the pivot pin 14 carried keyed to the arm 3 is hollow and thru it passes the wire 15 which connects the switch with the incandescent light 13. The switch comprises a fixed contact member 16 to which the wire 15 is connected and the spring contact member 17 to which the battery is connected. Both of these contact members are insulated from each other and the casing on which they are mounted. The hollow pivot pin 14 carries on the free end thereof a cam 18 made up of suitable insulating material and this cam is so positioned with relation to the arm 15 that when this arm is raised the cam rotates and forcesthespring contact member into contact with the fixed contact member 16 so that the electric circuit is closed and the light in the light head lighted as soon as the light is withdrawn from the pocket in the casing and placed in an elevated position.

When the light head is lowered and moved back into the pocket of the casing the reverse takes place because the swinging of the arm 15 downwardly rotates .the cam 18 on the pivot pin 14 away from the spring contact 17 so that this contact can move away from the contact 16 and open the circuit. This extinguishes the light automatically when the light head is placed back into the casing. So far I have described my invention as a portable lamp which can only be used when the light head is withdrawn from the casing so that it can be aimed at the particular spot which is to be illuminated by its light. In Figures 4: to 8 inclusive I have illustrated a slightly modified form of my portable lamp which is designed to make this same type of lamp suitable as a hand lantern.

As illustrated in thesefigures the construction of the casing, the light head and its mounting remain practically the same as that described in connection with Figures 1 to 3 inclusive. The difference between these two constructions is in the opening which is provided in the bottom 20 of the pocket 2 and the opening 21 which is provided in the back 12 of the casing. These two openings are in line with each other and the light head 6 when it is located within the casing. Light from the light in the light head is thus projected from the back of the casing 1 when the light in the light head is lighted.

In order to permit the lighting of the light in the light head while the light head is located within the casing, a manually operated switch member 22 is provided. This member comprises a short lever which projects thru an opening in the casing and is suitably pivoted on the inside of the casing. A cam member 23 is formed on the inside of the lever and this cam member is adated to force the spring contact member 17A in contact with the fixed contact member 16A when moved in one direction and allow the spring contact member 17A to spring away from fixed contact member 16A when moved in the opposite direction. The spring contact member 17 A is formed from the same strip of metal as the contact member 17 which is operated by the cam 18 and the fixed contact member 16A is formed from the same strip of metal from which the fixed contact member 16 is formed and their electrical connection with the battery and the incandescent light is the same asthat described in connection with Figure 3. In this way cam 18 will automatically operate the light circuit when the light head is raised out of or lowered into the casing while the manually operated switch member with its cam member 23 will operate the light circuit in the same way when it is desired to light the light or turn it off while the light head is located within the casing.
